Hi and congratulations on your new baby. I have a PR650 and they are fun. I use pre wound bobbins but without a huge hunt to see whats on the box I cant help. Ah its a L if that helps you. Sometimes you need to try a selection to see what suits your machine best. Good luck and have fun.

Great!!! Have fun! Wish I had one!

Lucky you! Don't forget check the upgrate. I had some time PR-600, but now I use PR-1000.

Congrats to you on your new addition. May it give you many years of happy stitching pleasure. I really recommend that you read the manual and if possible, take a class to make life easier. Be sure to use the correct bobbin size in the machine. My Babylock 6 needle uses a L size bobbin. It's a cinch to pop them in and take out the remains when it empties. You will really love doing bags on this machine. What a delight to not have to rip out seams. I hope you get to stitch very soon with it. Let us know how you like it.

Sweet! Congratulations...I know you will have a great time and many happy hours!

Congratulations. Have a great time stitching

Whoo Hoo! You go girl!

Congratulations Lyn! I would love to see it in action sometime, cheers Bev.

My sister in law has the PR600 and she uses and is happy with Echidna prewound bobbins cheers Betty2246
